The Fang Huang group focuses on developing the ultra-high resolution optical imagingsystems. For example, by developing the next generation single molecule switching nanoscopy (SMSN, a.k.a. PALM/STORM), we aim to create imaging systems capable of revealing dynamics of subcellular structures and large protein assemblies - previously impossible to visualize, with nanometer resolution in live cell. Using our innovative methods, we aim to understand the functional mechanisms of cellular processes such as cell division.
